CULTIVATOR.

SPECIFICATION 'forming part of Letters Patent No. 369,951, datedSeptember 13, 1887.

Application filed April 15, 1887.

T0 all whom it may concern:

Be it known that I, PHINEAS P. MAST, a citizen of the United States,residing at Springfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in Cultivators, of whichthe following is a specification, .reference being had therein to theaccompanying drawings.

This invention relates to improvements in cultivators, and it hasparticular reference to that class in which a cross -head carryingshovel-standards is used and held parallel to the axle by analignment-rod.

Letters Patent were granted to me December 21, 1886, and numbered354,717, and April 19, 1887, and numbered 361,307, for improve ments incultivators in which the cross-heads are so fitted to the beams orbeam-brackets as to overcome the twisting tendency between them andcarry two shovel-standards- The present invention is designed as animprovement upon them-noa however', in the sense of bettering theirconstruction, but rather in the sense of modifying some of the featuresthere shown and described and adapting them to another style of machine,and in the further sense of making certain additions necessary in thislatter style of machine, but not applicable to the former class.

With these ends in view the invention consists, first, of the cross-headconstructed with special reference to being pivot-ally connected to acultivator-beam and having three distinct parts or places fashioned toallow of the connection therewith of as many shovelstandards.

Secondly, theinvention consists, essentially, of the cross-head soconstructed, when combined with the beam or beam-bracket (these termsbeing synonymous in this specification, because the beam-bracket may bea part of the beam or may be separately made and attached to it) havinga portion to which the handle can be secured, and so located as that thethird shovel-standard will not be obstructed when the relative positionof the bracket and crosshead is changed; and, thirdly, the inventionconsists of the crosshead having enlarged upper and lowerbearing-surfaces, and a wall to which the third shovel-standard issecured, and located in the rear of said surfaces, and the beam-brackethaving a jaw fashioned with Serial No. 234,871. (No model.)

corresponding enlarged bearing-surfaces and partially encircling thecrosshead, the open end of the jaw allowing the wall or third standardto move laterally.

In the accompanying drawings, forming a part of this spccication, and onwhich like reference-letters `indicate corresponding parts, Figure 1represents a plan view of a portion of a cultivator, showing my improvedcrosshead and beam or beam-bracket; Fig. 2, a vertical transversesectional view of the crosshead and beam-bracket, the latter beingpartially shown in side elevation, and a portion of the intermediate orthird shovel-standard in like elevation; Fig. 3, an enlarged detail sideview of the crosshead, beam-bracket, and adjacent parts; and Fig. 4, arear view of the cross-head, showing portions of the standards attachedthereto.

The letter A designates a portion of the axle of any approvedcultivator, and the letter B the sleeve, and the letter C the collar,adjustably mounted thereon and having the vertical hub and lateral armto which the beam D and the alignment-rod E are respectively connected,as shown and described in my Letters Patent first above named.

It should be noted that any other Vform of connection than that herealluded to of the beam and alignment-rod to the axle may be employed,though this is the preferred form.

The letter F designates the rear end of the beam or the beam-bracketitself, and it cousists'of a metallic frame, when a bracket, (amalleable-iron I`rame,) and is provided with a jaw composed of upper andlower bearing portions or surfaces G, having holes for the reception ofaking or coupling bolt, H. 'It is further provided with flanges orstandards I and J, having, respectively, a bolt-hole and an irregularslot for the reception of bolts K and L to secure the handle M, the saidstandards being connected and strengthened by an intervening web, N. Thedisposition ot' the standards I` and J upon the bracket is such as togive the handle the proper direction laterally.

It will be observed that the rear ends of the jaws are disconnected. Itwill also be observed that the connection ol' the handle to' the beam orbeam-bracket is above and en- IOO tirely clear of the cross-head. Theabsence of any connection between the rear ends of the jaws and thisarrangement of the handle allow of the connection ot' the intermediateshovelstandard with the cross-head at a point substantially coincidentto the vlongitudinal vcenter of the beam, and between the upper andlower sides ofthe cross-head, without inter fering with the free lateralmovement of said standard.

The letter O designates my improved crosshead, constructed of metal,preferably of malleable iron, and ofthe shell-like form suggested inFigs. 2 and 4. At either end the head is constructed'with seats, towhich the shovelstandards are secured, and these seats arel either onevertical and the other horizontal or both horizontal or both vertical.The head is further provided with upper and enlarged bearing-surfaces,I), extended somewhat forward of the cross-head, as seen at Qin Fig. 2.l-Ioles are provided for the passage of the king or coupling boltalready alluded to. The t between the jaw and the surfaces P is smoothand snug, and thereby, together' with the fact that the surfaces areenlarged, all twisting between the cross-head and the beam-bracket isprevented, as explained in the patents to which reference has been made.

The letter S designates a wall occupying the interior of the cross-headand projecting slightly rearwardly, and constructed to form a seat, asseen in Fig. 2, to which is fitted the third orintermediateshovel-standard, T. The head is further provided with a lug, T', towhich the align ment-rod E connects at its rear end. The operation orjoint action of the alignment-rod and beam in respect to maintaining theparallelism between the cross-beam and the axle of the machine is asusual. The outer shovel-standards are bent or deflected outward, as seenin Fig. 4, for the purpose of bringing the shovels the proper distanceapart without unduly lengthening the cross-head.

It is obvious that the position of the intermediate standard on thecrosshead may be varied from that shown and described without departingfrom this invention, though that position is the preferred one, as itbrings the draft on aline with the beam and within the length of thecoupling or king bolt, as already suggested. The seats into which theshovel-standards are fitted and secured may of course also be varied inform, as many ways of connecting the standards will readily presentthemselves to those familiar with this branch of manufacture. l

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a cultivator, the combination, with a beam or beam -bracket havingportions to which the handle may be secured and constructed with a partadapted to engage with a cross-head, of the cross-head constructed witha matching part and having seats for two outer and an intermediateshovelstandard, and standards and their shovels for said seats.

2. In a cultivator, the combination, with a beam or beam-bracket havinghandle portions,

of a cross-head pivoted to the beam or beam.

bracket in a different plane from that of the handle portions and havingseats for two outer shovel-standards and an intermediate shovelstandard,and shovel standards and their shovels for said seats.

3. In a-cultivator, the combination, with a beam or beam-bracket havinghandle portions,

side and beyond the jaw.

5. In a cultivator, the combination, with a beam or beam-bracket, of across-head pivoted thereto and constructed with two outer shovelstandard seats and an intermediate shovelstandard seat, and shovelshaving .standards secured to said seats.

6. In acultivator, the combination, with the beam or beam-bracket havinghandle-standards and a jaw whose upperand lower members are enlarged toform bearing-surfaces, of a cross-head whose upper and lower portionsare also enlarged to form bearing-surfaces,piv otally mounted in saidhead, and having outer shovel-standard seats, and an intermediateshovel-standard seat located between the'said upper and lower portions.

.7. In a cultivator, a cross-head having a king-bolt hole and two outershovel-standard seats,and an intermediate shovel-standard seat locatedbetween the upperand lower portions of the head and substantially inline with the said hole.

8. In a cultivator, a beam or beam-bracket formed into a jaw at its rearend, the upper and lower members of which are enlarged to formbearing-surfaces and have a king-bolt hole and handle-standardsprojecting from the upper member. y

In testimony whereof I aflix my signature in presence of two witnesses.
